Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 5451116 terminal block plug is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (IEC: 12A minimum), voltage rating (IEC: 630V minimum), and wire gauge acceptance (12-30 AWG / 0.2-2.5mm²)
• Mechanical Compatibility: 17-position configuration, 0.200" (5.08mm) pitch, 90° wire entry orientation, and free-hanging in-line mounting
• Termination Interface: Screw-based termination with M3 screw size and 0.5-0.6 Nm torque specification
• Physical Dimensions: Insulation height of 1.024" (26.01mm), wire strip length of 7mm, and female socket contact type
• Regulatory Compliance: RoHS compliance and UL94 V-0 flammability rating

The substitute part Phoenix Contact 1792391 meets all these criteria while offering an active product status and enhanced termination technology (Rising Cage Clamp).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1792391 is a direct functional equivalent to the 5451116 for applications requiring a 17-position, 5.08mm pitch terminal block plug with 90° wire entry and free-hanging in-line mounting. Both parts maintain identical electrical specifications at IEC ratings (12A, 630V) and mechanical dimensions (1.024" insulation height, 7mm wire strip length).

The primary distinction is product lifecycle status: the 5451116 is obsolete, while the 1792391 is active. The 1792391 employs Rising Cage Clamp termination technology in place of standard screw termination, offering enhanced wire retention characteristics while maintaining the same M3 screw size and 0.5-0.6 Nm torque specification. The 1792391 also demonstrates improved UL current rating (15A versus 12A), providing additional margin for UL-regulated applications.

Both parts are RoHS compliant with UL94 V-0 flammability ratings and MSL 1 moisture sensitivity classification, ensuring regulatory alignment for industrial control and power distribution applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1792391 directly replace the 5451116 in existing installations?

A: Yes. Both parts share identical pitch (5.08mm), position count (17), wire entry angle (90°), mounting configuration (free-hanging in-line), and electrical ratings at IEC specifications (12A, 630V). Physical dimensions and screw termination parameters are equivalent, enabling direct mechanical and electrical substitution.

Q: What is the difference between the termination styles listed for these parts?

A: The 5451116 uses standard screw termination, while the 1792391 uses Screw - Rising Cage Clamp termination. Both employ M3 screws with identical torque specifications (0.5-0.6 Nm). The Rising Cage Clamp design in the 1792391 provides enhanced wire retention during the termination process.

Q: Are there packaging differences between these parts?

A: The 5451116 is listed with no specified packaging designation, while the 1792391 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact functional compatibility.

Q: Why does the 1792391 have a higher UL current rating (15A) compared to the 5451116 (12A)?

A: The 1792391 represents a newer design iteration within the COMBICON MVSTBR series with improved electrical performance characteristics. The IEC current rating remains 12A for both parts, ensuring consistency in international standards compliance. The elevated UL rating reflects enhanced design margins in the 1792391 for North American applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5451116 and 1792391 are RoHS compliant with UL94 V-0 flammability ratings, meeting environmental and safety requirements for industrial applications.

Q: What wire gauges are compatible with these terminal blocks?

A: Both parts accept wire gauges from 12-30 AWG (0.2-2.5mm²), with a wire strip length requirement of 7mm for proper termination.
